If you're getting it from starting fluid, there is no home way to get the hydrocarbons out (the shake with water thing does not work), and thus, you will get a combination of the effects of ether, and those of the much more toxic solvents (think, sniffing glue). So, don't use ether from starting fluid. The high isn't that great (mainly because of side-effects from the other crap).
If you're getting real ether, should be worth doing.
Be aware that it is EXTREMELY EXTREMELY FUCKING FLAMMABLE. It evaporates very rapidly, and the vapors are much heavier than air, and so will crawl along the floor.
I'm not sure what it's method of action is. It's a centrally acting anesthetic and sedative, causes euphoria, loss of coordination, etc. I never got hallucinations in the trippy sense. Some visual artifacts maybe, but nothing like a hallucinogen or deliriant. I'd compare it most closely to nitrous, only obviously much longer acting.
